Abstract

Abstract: A 33-year-old male patient having multiple drug allergies but well tolerated to Hepatitis-B vaccine (vaccinated in April 2016) on receiving a second booster dose of Hepatitis-B vaccine (GeneVac-B) within 10 days of Covishield first dose immunization experienced a sharp rise in blood pressure, facial flushing, heaviness of head and eyes, dizziness, and palpitation accompanied with rashes in the right arm after 30 min of receiving the Hepatitis-B vaccine. Since no data is available on coadministration of other vaccines along with Covishield, serious investigations are commendable to deduce potential adverse events for universal acceptance.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
